The crisis in forensic science, here:


And an excerpt from a separate 2018 report:
Fingerprint [identification] susceptible to analyst bias, and has a high false-positive rate.

Firearm/toolmark identification currently falls short of the criteria for foundational validity.

Bite-mark evidence lacks any scientific foundation.

Impression/pattern analysis of shoes, tires, etc. unsupported by statistical surveys, and may mislead jurors.

Fiber analysis no set standards.

Hair analysis a recent review by the FBI found that 90% of cases involving hair analysis contained erroneous statements.

    I had no idea forensic scientists used magician's tricks. I am pretty sure I'd accept their analysis (e. g. in Chris's article) over a claim that it is a trick. Besides, in my opinion, it does look... more

            Dan, I am sorry I was not clear in my previous response. I have no problem with the conservative or liberal nature of the article. I have a problem with someone using a media article as scientific... more

              Rocky, not to put too fine a point on it but people criticizing aspects of forensics are themselves scientists. In fact, one of the major reports was issued by the US National Academy of Sciences.... more

                    The information you just spouted came from the report you said you would keep confidential . It did not from the two articles you just posted. Good try.

      Forensic science is loaded with tricks, not to mention bogus science, like blood splatter and bite evidence.
